APPI lamp drive assembly
Notice:
To prevent damage to the corona pin and lamp assembly, ensure that the
lamp assembly does not touch the corona pin when the source enclosure door is
closed.
The UV lamp, which you ignite via a control in the MassLynx software Tune window, provides a
constant photon output. You vary the intensity of incident radiation upon the sample molecules by
adjusting the distance between the UV lamp and probe tip.
